A UAC Base themed map. Not too hard, but offers a nice challange. Difficulty settings do not matter. Only tested in GZDoom, but likely to work with all other source ports.
Well, it seems that a UAC Base has been infested--again--with goddamn demons! To hell with those suckers! And it looks like you're gonna have to clear 'em out. Pump that shotgun, and load that chaingun, 'cuz you got some clean up to do!
